JOHN F. BO'WDITCH, OF BOSTON", MASSACHUSETTS.

POWDER HOLDER AND DISTRIBUTER.

To all whom it may concern:

Be it known that I, JOHN F. BOWDITGH, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Powder Hold ers and Distributers, of which the following is a specification.

This invention relates to a holder for powdered materials adapted to be held by the hand of the user, and is employed to distribute the contained material which may be, for example, a dust-laying powder to be sprinkled on a floor before sweeping.

The invention has for its object to provide a holder adapted to contain a considerable quantity of the material and to segregate from the mass of material a predetermined charge to be distributed at one time, the body of the material being confined so that it cannot escape while the segregated charge is being distributed.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings which form a part of this specification,Figure 1 represents a side elevation of a powder holder and distributer embodying my invention, the distributing chamber being open for the discharge of material and closed against the reception of material from the body of the holder; Fig. 2 represents a section on line 22 of Fig. 1; Fig. 3 represents a section on line 33 of Fig. 1; Fig. 4E represents a section similar to Fig. 3 showing the distributing chamber closed against the discharge of material and connected with the body of the holder; Fig. 5 represents a perspective view of a portion of the holder; Fig. 6 represents a section on line 66 of Fig. 1; and Fig. 7 represents a section similar to Fig. 6 showing the gate valve hereinafter referred to, forced outwardly.

Similar reference characters indicate the same or similar parts in all the figures.

In the drawings, 12 represents a tubular holder which may be of any suitable length and is provided with a closed end or bottom 13, the opposite end being open.

14 represents an outlet orifice formed in one side of the tube near its open or outer end.

15 represents a segmental slot formed in the wall of the tube below the outlet 14:, the ends 15 of said slot constituting stops which cooperate with a gate valve, as hereinafter described.

16 represents a tubular valve which is rotatable on the outlet-containing portion of the tube and closely fits the latter. Said valve is provided with an orifice 17 adapted to register with the outlet 14, and with a head 18 which closes the outer end of the tu e.

19 represents a gate valve which is a flat disk, preferably of sheet metal, of sufficient diameter to constitute a partition substantially dividing the interior of the tube into a main or storage chamber 20, and a distributing chamber 20*, the latter being a part of the tube which contains the outlet 14. The

margin of the gate valve 19 projects into the slot 15 when the valve is closed, as shown by Fig. 6.

21 represents a rod or stud attached to the head 18 of the tubular valve and extending therefrom, into the tube through the distributing chamber 20*, and through an orifice formed for its reception in the gate valve 19. The stud 21 is arranged eccentrically or at one side of the longitudinal center of the tube, the orifice in the gate valve being correspondingly arranged, the arrangement being such that when the tubular valve is in the position shown by Figs. 1, 2, 3 and 6, the stud 21 is located about midway between the stops 15 and the gate valve is in its closed position, the orifice 17 of the tubular valve being at the same time in coincidence with the stud 14, so that the tubular valve is open.

A rotary movement of the tubular valve from the position last described, in the direc tion indicated by the arrow in Fig. 6, will cause a lateral movement of the stud 21. The gate valve'19 is moved edgewise by the lateral movement of the stud in the same direction, and therefore swings outwardly until its edge strikes a stop 15 formed by one end of the slot 15, as shown by Fig. 7. This occurs when the tubular valve has been turned far enough to close the outlet 14, as shown by Fig. 4. The chambers 20 and 20* of the tube are thus connected so that material may be transferred from the chamber 20 to the chamber 2O by a suitable manipulation of the tube. After the material has been transferred, a continued lateral movement of the stud 21 by a continued rotation of the tubular valve in the direction indicated by the arrow in Fig. 7, will press the gate valve 19 against the stop 15 last referred to, said stop preventing further outward movement of the gate valve and causing it to swing inwardly in the direction of the arrow marked thereon in Fig. 7, so that when the tubular valve reaches its open position the gate valve is closed. The charge of powder in the chamber 20 may now be distributed through the outlet.

The material of the tube is preferably paste board or other suitable stiff and inexpensive material, the valves 16 and 19 being preferably made of sheet metal.

I do not limit myself to the described connections between the rotary valve and the gate valve whereby a rotary movement of the rotary valve causes first an outward swinging movement of the gate valve against an, end of the slot 15, and a continuation of said movement thereafter causes an inward swinging movement of the gate valve, as any other suitable means for accomplishing this result may be employed.

The reason why a rotary movement of the tubular valve 16 causes an outward movement of the gate valve 19 until the latter reaches the position shown by Fig. 7, is as follows :The stud 21 being eccentric to the tubular valve 17, is caused by the rotation of the latter to move in a circular path ororbit, concentric with the axis of rotation of the tubular Valve. The stud closely fits the orifice in the gate valve through which it passes, so that the orbital movement of the stud causes it to exert pressure on the gate valve, tending to move the latter edgewise. The greater part of the periphery of the gate valve projects into the slot shown by Fig. 6 at the commencement of the orbital movement of the stud, hence the gate valve follows the path of least resistance, and swings outwardly through the slot during the greater part of the said orbital movement and until it reaches the position shown by Figm'f, when it abuts against a stop 15, and is caused to swing inwardly during the completion of the orbital movement of the stud to the position shown by Fig. 6.

I claim 1. A powder holder and distributer comprising a tube having a side outlet near one end and a segmental peripheral slot below said outlet, a tubular valve rotatable on the outlet-containing portion of the tube and adapted to open and close said outlet, an oscillatory gate valve movable edgewise in the tube and slot and adapted to confine a charge of material in the said outlet-containing portion, and means connecting said valves whereby a rotary movement of the tubular valve causes first an outward charge-releasing movement of the gate valve until the latter contacts with an end of the slot, and then an inward, charge-confining movement of the gate valve, said end constituting an abutment which causes a continuation of said rotary movement to swing the gate valve inwardly to its chargeconfining position.

2. A powder holder and distributer comprising a tube having a side outlet near one end and a segmental peripheral slot below said outlet, a tubular valve rotatable on the outlet-containing portion of the tube and adapted to open and close said outlet, an oscillatory gate valve movable edgewise in the tube and slot and adapted to confine a charge of material in the said outlet-containing portion, and a stud engaged with the gate valve and with the tubular valve, and arranged eccentrically within the latter, said stud being movable laterally by rotary movements of the tubular valve and adapted to impart a lateral movement to the stud and through the latter, first, an outward swinging movement to the gate valve until the gate valve contacts with an end of the slot, and then an inward, chargeconfining movement of the gate valve, said end constituting an abutment which causes the gate valve, when moved by the stud, to swing inwardly to its charge-confining position.

In testimony whereof I have affixed my signature, in presence of two witnesses.
